Process Control Dynamics please help and explain in detail

A process has a transfer function with the following equation G(s) = K(T2S+1) with K (T25+1)(T28+1) 2, 1 = 10, T2 = 2. If t, has the following values, Case i: ta = 20 Case ii: Ta = 4 Case iii: Ta = 1 Case iv: Ta -4 2 Use OCTAVE to simulate the responses for a step input of magnitude 0.5 and plot them in a single figure
